San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.
San Diego Rat Control Tip of The Week
Do Rats Bite Human Necks?
Rodents are omnivorous animals. Their diet is mainly based on seeds, insects, and small animals. In order to hunt, they usually bite their victims' neck to neutralize them and suffocate them until they finally die. Seeing this behavior, some people think that rats will also bite human necks, but this is extremely uncommon.
There are cases where a rat has bit a child's face, neck, and hands. This type of aggressive behavior is often seen when rodents feel that the child's movement could be a threat. On the other hand, sometimes this happens when children are dirty and have food remains on them, thus confusing the rodents.
Complications Of A Rodent Bite
A rat bite can hardly suffocate a human being, but it can have other serious complications produced by the bacteria they carry. Symptoms appear within 3 weeks after the bite when the infected wound heals.
An infectious disease can begin with increased body temperature and chills. Within 3 to 4 days after the onset of the fever, there could be rash, systemic damage to different organs such as heart or brain, and visible swelling of the lymph nodes.
Bites are not the only way a rodent can transmit diseases. Direct contact through scratches produced by infected rats is usually quite harmful as well. However, it is more common to become infected by ingesting food or water contaminated with an infected rats' feces or urine.
Pest control is necessary to look after one's own health and that of your entire family, including household pets. There are cases of domestic animals such as dogs and cats that, when biting rats, can also become contaminated with these diseases which can be deadly.
